Power Steering Pump Choice

Now trying to determine what parts I'm needing to have a complete PS pump setup. Literally the only part I have in the whole system is the gear box itself. No pump, no pulley, no brackets, belts, hoses...nothing. So far, I haven't found anything in either my shop manual or the parts manual that shows what else I need to locate. I don't know what I don't know. I have a call in to Wildcat Auto Wrecking (they work closely with Firm Feel) for some help, but I will still need to have some idea of what to tell them I need. Anyone know where there is an exploded view of the whole setup?
